Answer:
Step 1: Remove parentheses by multiplying factors.
= (x * x) + (1 * x) + (2 * x) + (2 * 1)
Step 2: Combine like terms by adding coefficients.
(x * x) = x2
(1 * x) = 1x
(2* x) = 2x
Step 3: Combine the constants.
(2 * 1) = 2
Step 4: Therefore, Simplifying Algebraic Expression is solved as
= x2 + 3x + 2.
Step-by-step explanation:
answer isx2 + 3x + 2.
Does 3 (x-1) = 2x + 9 have one solution, no solution, or infinite solutions?
Answer:
one solution
x = 12
Step-by-step explanation:
3 (x-1) = 2x + 9
3x - 3 = 2x + 9
subtract 2x from each side of the equation:
x - 3 = 9
add 3 to each side:
x = 12
Step-by-step explanation:
3x-3=2x+9
3x-2x=9+3
x=12
only one solution
Em uma escola,estudam em tres periodos 1256 meninas e 1593 meninos. quantos alunos estudam nessa escola?
Answer:
I will answer in English.
This can be translated to:
In a school, 1256 girls and 1593 boys study in three periods. how many students study at that school?
This means that we have a total of:
(1256 + 1593) students = 2849 students, divided in 3 periods.
So the total number of students in that school is 2849
And the number of students per period is:
2849/3 = 949.7
Because we can only have whole numbers here, we can say that in each period there are around 950 students.

oi can someone help me with this one ^{2}-12x-28=0
This is still pretty confusing for me
Answer:
Both answers should be -2 and 14.
Step-by-step explanation:
Using the quadratic formula:
[tex]x^{2}-12x-28=0\\\\x=\frac{-(-12)+-\sqrt{(-12)^2-4(1)(-28)} }{2(1)}\\\\x= \frac{12+-\sqrt{144+112} }{2}\\\\x= \frac{12+-\sqrt{256} }{2}\\\\x= \frac{12+-16 }{2}\\\\x=6+-8[/tex]
Therefore:
[tex]x_{1} =6+8=14\\x_{2}=6-8=-2[/tex]

if cos 0 = -3/4 and 0 is in quadrant iii then sin 0 is equivalent to
Answer: - radical 7 / 4
Step-by-step explanation:
draw a triangle in quadrant III
plug in correct terms
use Pythagorean theorem
to simplify down to find the opposite angle
b= rad 7
The sum of the squared lengths of the other two sides of a right triangle equals the square of the hypotenuse's length, which can be defined as follows:
Finding the sin θ value:
[tex]\to \cos \theta =-\frac{3}{4}[/tex]
[tex]\to \sin \theta =?[/tex]
[tex]\sin \theta = \frac{opposite}{hypotenuse}\\\\\cos \theta =\frac{hypotenuse}{adjacent}\\\\[/tex]
therefore
hypotenuse= -3
adjacent= 4
Using the Pythagorean theorem to find the opposite:
Hypotenuse²= Adjacent²+ Opposite²
[tex]-3^2= 4^2+x^2\\\\9=16+x^2\\\\x^2= -16+9\\\\x^2=-7\\\\x= -\sqrt{7}\\\\[/tex]
Therefore the value of sin θ [tex]= \frac{\sqrt{7}}{-3}= \frac{\sqrt{7}}{3}[/tex]

You find a piece of wood that is 7.24 long and your friend finds one that is 4.65cm how long would they be if you attached them?
Answer:
They would be 11.89cm long.
The total length of the two pieces of wood is 11.89cm.
When two pieces of wood are found by different people,
The total length of both pieces can be calculated by adding their respective lengths.
In this case,
One person found a piece of wood that is 7.24cm long,
While the other person found a piece that is 4.65cm long.
To determine the total length of both pieces of wood,
Simply add 7.24cm and 4.65cm together.
The sum of these two measurements is,
4.65 + 7.24 = 11.89cm.
That would be the total length of the two pieces of wood if they were attached.
Therefore, if we want to attach these two pieces of wood together, we will need a length of material that is at least 11.89cm long.

Step-by-step explanation:
find the H.C.F of : 120 and 150.
Answer:
30
Step-by-step explanation:
You can use prime factorization to find the HCF of both numbers.
First, list out the prime factors of both numbers.
120: 2³ × 3 × 5
150: 2 × 3 × 5²
Next, find the common prime factors of both numbers and multiply them together.
common prime factors: 2 × 3 × 5 = 30
Answer:
30Step-by-step explanation:
Find the prime factorization of 120120 = 2 × 2 × 2 × 3 × 5Find the prime factorization of 150150 = 2 × 3 × 5 × 5To find the HCF, multiply all the prime factors common to both numbers:Therefore, HCF = 2 × 3 × 5HCF = 30The greatest common factor (GCF) is also known as greatest common divisor (GCD) or highest common factor (HCF).What is the definition of homonym?
Answer:
a group of words that share the same spelling and pronunciation but have different meanings.
Answer:
If they are pronounced the same then they are also homophones (and homonyms) – for example, bark (the sound of a dog) and bark (the skin of a tree). If they are pronounced differently then they are also heteronyms – for example, bow (the front of a ship) and bow (a ranged weapon).

WITH STEPS!
Answer:
When we have something like:
[tex]\sqrt[n]{x}[/tex]
It is called the n-th root of x.
Where x is called the radicand, and n is called the index.
Then the term:
[tex]\sqrt[4]{16}[/tex]
is called the fourth root of 16.
And in this case, we can see that the index is 4, and the radicand is 16.
At the end, we have the question: what is the 4th root of 16?
this is:
[tex]\sqrt[4]{16} = \sqrt[4]{4*4} = \sqrt[4]{2*2*2*2} = 2[/tex]
The 4th root of 16 is equal to 2.
